2. The method of claim 1 , wherein the preferred roaming partner identifier comprises a radio access network (RAN) identifier identifying a RAN.

3. The method of claim 1 , wherein the MSIN is included in a set of two or more MSINs, wherein said set of two or more MSINs is assigned by the identified infrastructure provider to the preferred roaming partner that operates at least one of said two or more radio access networks.

4. The method of claim 1 , wherein the MSIN is included in a set of at least one-hundred consecutive MSINs, wherein said set of at least one-hundred consecutive MSINs is assigned by the identified infrastructure provider to the preferred roaming partner that operates at least one of said two or more radio access networks.
